Abstract
Methods to control power to a cooking appliance are provided. The methods include monitoring a power signal to the portion of the cooking appliance, including monitoring a current and/or voltage of the power signal. The methods also include selectively interrupting power to the portion of the cooking appliance in response to: determining that the current fails to exceed a current threshold within a time threshold, determining that the voltage fails to exceed a voltage threshold within a time threshold, determining that the current exceeds a current threshold for a first time threshold but fails to exceed the current threshold for a second time threshold, and determining that the voltage exceeds a voltage threshold for a first time threshold but fails to exceed the voltage threshold for a second time threshold. The methods also include temperature sensing and controlling the power signal based thereupon.
